The Duro 6L Backpack is built to carry our essential items for our next trail run or ride. It's little, but mighty with bounce-free stability and utilitarian comfort that lets us clock in miles on end. A durable nylon construction stands up to snags and hits on trees or rocks while we're scrambling or weaving through the woods and up mountains, and the included Hydraulics 1. 5L reservoir with attached hose and sternum magnet lets us go hands-free for easy drinking when we're all tied up tackling obstacles on the trail.
